To all whom it may concern:

Be it known that I, SAMUEL M. ADAMS, of

,the city and county of New York, State of New York, have invented a newand useful Iniprovement in the Art of Ornamenting Glass: and I do herebydeclare that the following is a full and correct description thereof.

The object of my invention is to facilitate the art of ornamenting glassby acid etching, and to enable the process to be conducted by those Whoare not skilled in ornamental drawing or designing.

In carrying out my invention, I first-cover the glass With metal foilrolled smoothly upon the glass, to which it will adhere sufficiently bythe use of suitable slightly adhesive mucilage. I then place upon thefoil a pattern-plate of sheet metal, and holding it firmly cut the foil,as indicated by the pattern, with a cuttingtool, the cutting-toolfollowing the edges of the pattern-plate, and being guided by it. Thefoil thus cut out may then be removed and the acid applied as usual inetching glass by acid.

I do not claim, broadly, the use of patternplates for producingornamental designs upon glass; neither do I claim the employment ofacids for engraving or etching upon glass or metal; but

What I claim as new in the art or process of ornamenting glass isi l.Attaching temporarily with mucilage or other suitable adhesive substancemetallic foil to the article to be ornamented, then producin g upon suchfoil and surface the desired pattern by means of a stencil orguideiplate and suitable cutting-tool.
